Its ID gene: the stretch scientists read to tell microbes apart. Each bar is one letter of its DNA. Every species has its own order of letters, so the pattern works like a fingerprint. Close relatives share most of it.

16S rRNA gene, V4 region: the 253 letters between the standard primers (515F/806R), which are the same in every species. One reference sequence; strains can differ by a letter or two. NCBI NR_117905.1

Its genome

Genome · 6.0 million letters · 48% G+C
Shortest we have Mycoplasmoides genitalium 0.6M
⋮ 2,219 shorter
Acetatifactor muris 6.0M
⋮ 132 longer
Longest we have Bradyrhizobium altum 9.8M

Among the largest for a gut microbe: longer than 94% of the 2,354 we have genomes for.

48% G+C, higher than 50% of gut microbes.

To scale: if its ID gene were 1 cm long, its genome would stretch 40 meters. Yours would stretch 21 kilometers. One reference genome; strains vary. NCBI GCF_024623325.1

What it can do

Makes
  • Can make butyrate A short-chain fatty acid that feeds the cells lining the colon.
  • Can make propionate A short-chain fatty acid, mostly used by the liver.
